My boy is the same. He doesn't like water. I tried using an old baby bottle with a bigger open teat but that can still be hit and miss. Just offering it lots of times throughout the day, you never know when they'll want it
Have you tried the Tum tum beaker with straw? I changed to this and she now drinks lots of water through it xxx the straw has no valve either so easier for the water to pull through straw. She mastered it straight away xxxx
Tum tum straw cup x
What cup is the tum tum one? Is it the trainer cup or the one with animals on the top lol
I'm having the exact same issue, do you find your baby is getting quite constipated too?
